Actually, it should not load the graph when graph_generator is loaded.
Anyway, I think that if it was the case, the error would be printed a
Sage's startup and not when I call the function, which is my current
situation :-/
When I remove all the docstrings, this functions is pretty simple :
def WorldMap(self):
return sage.structure.sage_object.load("graph_world.sobj")
I rebuild I start my branch without the slightest problem, but when I
type g=graphs.WorldMap()
I get :
sage: g=graphs.WorldMap()

And I can not understand why, nor how I should do to bypass it :-/
